Coal quality testing is the process of analyzing coal samples to determine their physical and chemical properties. This includes measuring moisture, ash content, calorific value, total sulfur, volatile matter, and fixed carbon. These parameters are essential to assess whether the coal meets industry standards for power generation, metallurgy, or cement industries.
Why is Coal Testing Important?
Coal varies by origin, age, and type — and its quality directly affects combustion efficiency, environmental impact, and operational costs. Without reliable coal laboratory analysis, you risk using substandard material, regulatory issues, or contractual penalties in export and local markets.
Who Needs Coal Quality Testing?
- Coal mining companies for production control
- Trading companies for purchase verification
- Power plants to confirm fuel standards
- Cement and smelter industries to secure consistent fuel specs
- Geological consultants in exploration reporting
Where is the Testing Done?
At Lithoterra Geoservices, we partner with certified coal laboratories in Indonesia equipped with calibrated, industry-standard equipment for accurate, internationally recognized results.
When Should You Test Coal?
- Before shipment (pre-shipment inspection)
- After production (stockpile quality control)
- During exploration drilling (resource evaluation)
- For periodic quality verification in long-term supply contracts
How Do We Test Coal Quality?
Samples are collected based on ASTM and ISO standards, then tested for:
- Moisture (Total, Inherent, Surface)
- Ash Content
- Calorific Value (Gross & Net as Received)
- Volatile Matter
- Fixed Carbon
- Total Sulfur
Results are delivered in a complete coal assay report with full analysis tables and standard compliance notes.
